The Socorro Wren ("Troglodytes sissonii") is a species of bird in the Troglodytidae family.It is endemic to Socorro Island, Mexico. It was formerly placed in "Thryomanes" but was moved to "Troglodytes" considering "manners, song, plumage, etc" [Howell & Webb (1995)] and by biogeography and mtDNA NADH dehydrogenase subunit 2 sequence analysis [Martínez Gómez "et al." (2005)] .

Its natural habitats is the tropical arid "Croton masonii"-prickly pear [Probably Engelmann's Prickly Pear ("Opuntia engelmannii"): Bradstrom & Howell (1956)] shrubland and occasionally the more humid forest. It appears to prefer this habitat, limiting its presence above 600 m (2000 ft) although it does range over the whole island. [Brattstrom & Howell (1956), BLI (2004)]

During visits in 1953, the birds were observed to be out of breeding season in mid-March; territorial males were observed in mid-late November.Brattstrom & Howell (1956)]

The main limiting factors are by habitat destruction due to feral sheep and predation by feral cats. In 1953, it was noted to be unwary. However, the IUCN does not yet consider it threatened, because especially compared to the larger birds of Socorro, it has fared not too badly and remains among the most common local landbirds. [BLI (2007)]
